Question

= Find the surface area of a cube having an edge 1.5 m

​

Answer 1

Given :-

• Edge of the cube = 1.5m

To Find :-

• Surface area of the cube

Solution :-

$\orange{ \sf{edge \: of \: the \: cube \: (a) = 1.5 \: m}} \\ \orange{ \sf{surface \: area \: of \: the \: cube \: = 6 {(a)}^{2} }{m}^{2} } \\ \sf{putting \: the \: value \: of \: edge \: in \: te \: formula \: - } \\ \orange{ \sf{6 \times {1.5}^{2} = 6 \times 1.5 \times 1.5 = 6 \times \frac{15}{10} \times \frac{15}{10} }} \\ = \orange{ \sf{ 6 \times { \cancel{ \frac{15}{10} }} \times { \cancel{ \frac{15}{10} }}}} = \orange{ \sf{6 \times \frac{3}{2} \times \frac{3}{2} }} = \orange{\frac{6 \times 9}{4}} = \orange{\frac{3}{2} \times 9} = { \sf\orange{13.5 {cm}^{2} }}$

THE SURFACE AREA OF THE CUBE = 13.5 cm²

Answer 2

Answer:

The total surface area of the cube will be 13.5 m²

Step-by-step explanation:

Here the edge of the cube is given to be 1.5  m

We have to find the surface area of the cube

total surface area of cube = 6a², where a is the side of the cube

                                           = 6(1.5)²

                                           = 6 × 2.25

                                           = 13.5 m²
